El objetivo de este trabajo fue estudiar la influencia de diferentes niveles de estrés térmico del ambiente, incluyendo niveles de confort (25 °C), estrés por calor (28 °C), calor moderado (31 °C), calor alto (34 °C) y calor severo (37 °C), en el desempeño de pollos de engorde en el la última fase de crecimiento (22-42 días), alojados en cámaras climáticas. Se determinaron los parámetros fisiológicos y de comportamiento de los pollos (ganancia de peso (WG), ganancia de peso diaria (DWG), consumo de alimento (FI), índice de conversión alimenticia (FC), mortalidad (MORT), porcentaje de carcasa con relación a la edad y peso corporal (BW), carcasa (CAR), pecho (Bre), muslos (Drum), alas (Win)), de acuerdo a los rangos específicos de temperatura; y se calculó el Índice de Temperatura de Globo Negro y Humedad (ITGH), para el control y evaluación térmica de los tratamientos. En general, las aves mantenidas en temperatura entre 25-28 °C, durante las tres últimas semanas de vida, se comportaron mejor que las expuestas a otras situaciones, e indicando que esta podría ser la temperatura ambiente deseada para las aves en su fase final, en comparación con los otros tratamientos, incluidos los que se mantuvieron a la temperatura recomendada como confort térmico durante todo el período experimental.

Abstract: The aim of this study was to assess the effect of seed treatment at different levels of physiological quality with amino acids on the performance of seeds and plants in the field. The experimental design was a randomized complete block design with four replications involving a combination of two factors. Factor A consisted of seed lots of three levels of physiological quality (high, intermediate, and low) and factor B consisted of five doses of a commercial product based on amino acids used in seed treatment.Seeds of different levels of physiological quality were treated with a commercial product (C.P.) at doses of 0, 200, 400, 600, and 800 mL C.P. 100 kg−1 of seeds. After seed treatment, the physiological performance was assessed in the laboratory and then the seeds were sowed in the field aiming at assessing plant performance, yield components, and productivity. Seed treatment with amino acids does not promote the physiological performance of seeds and plants in the field. The productivity of isolated soybean plants from seed lots of a high physiological quality is 15% higher than that of plants from seed lots of a low physiological quality.

This study aimed to recognize the different effects of administration of sodium tungstate in developmental indices of the offspring till weaning. Four groups of Albino Wistar pregnant female rats were used, the first one was control while the remaining three groups intubated with Na- tungstate 75, 150 and 300 mg/ kg/ day respectively since the first day of parturition throughout 21 days. Results referred to an elevation in weight gain of rat dams treated with 75 mg/ kg while weight gain of offspring elevated in both doses of 75 and 300 mg/ kg throughout 21 days, teeth and eye orifice were observed in doses of 75 and 300 mg/ kg faster than control while the mean of ovary weight elevated in both 75 and 300 mg/ kg however the dose 300 mg/ kg revealed the less value of testes weight. The conclusion of present study is that Na- tungstate has positive effects on developmental indices in offspring when administered through nursing until weaning.

Base Superalloy

Recently we have been investigating a class of nickel-base superalloys which possess substantial room temperature ductility. This improvement in ductility is directly related to improvements in grain boundary strength due to increased boundary cohesion through control of detrimental impurities and improved boundary shear strength by controlled grain boundary micros true tures.For these investigations an experimental nickel-base superalloy was doped with different levels of sulphur impurity. The micros tructure after a heat treatment of 1360°C for 2 hr, 1200°C for 16 hr consists of coherent precipitates of γ’ Ni3(Al,X) in a nickel solid solution matrix.
